CALPUFF Model, History and Current Status – Part 1

on .

CALPUFF 2003 2019

   Dispersion modelling is a key element of most odour assessments around the world. There are 2 or 3 well known dispersion models developed for regulatory assessments of which the most well-known are, AERMOD and CALPUFF. Because both models have been US EPA guideline models until CALPUFF was recently removed in 2017, they are routinely used in most air quality and odour assessments.

   This article highlights the history and background behind CALPUFF and, the reason for its removal as a US EPA guideline model. Concerns with AERMOD for odour assessments will be presented in a separate document, Part 2.
